High blood pressure is one of the biggest health problems in the world. Millions of people live with it every day, and many do not even know they have it because it usually causes no clear symptoms.
Over time, high blood pressure can quietly damage the heart, brain, kidneys, and blood vessels. It greatly increases the risk of heart attack, stroke, heart failure, and kidney disease.
The good news is that high blood pressure can often be controlled with healthy lifestyle changes and the right medicines. However, many people struggle to keep their blood pressure at a healthy level because they do not receive enough support or regular follow-up.
A international study has found that doctors may not always be the healthcare professionals who can provide the greatest help with long-term blood pressure control.
Researchers from Tulane University discovered that pharmacists and community health workers achieved the best results when helping people manage hypertension, another name for high blood pressure.
The research was published in the journal Circulation: Cardiovascular Quality and Outcomes. The research team examined information from 100 clinical trials carried out around the world.
These studies tested different ways healthcare professionals helped patients lower their blood pressure. The researchers compared programs led by doctors, nurses, pharmacists, community health workers, and teams made up of several healthcare professionals.
The results showed that every group helped patients improve their blood pressure. This is encouraging because it means many different healthcare workers can play an important role. However, pharmacist-led programs produced the largest improvements.
On average, these programs lowered systolic blood pressure, the top number in a blood pressure reading, by 7.3 mmHg. Community health workers were almost as successful, lowering the top number by an average of 7.1 mmHg.
Nurses and several other healthcare professionals also helped, but their average reductions were usually between 2 and 3 mmHg. Pharmacists and community health workers also performed especially well at lowering diastolic blood pressure, the bottom number in a blood pressure reading.
For adults, a systolic blood pressure of 130 mmHg or higher is generally considered high. Even a small drop in blood pressure can make a meaningful difference. Lowering blood pressure reduces the chances of heart attacks, strokes, kidney disease, and other serious health problems.
Because of this, a reduction of around seven points is considered important and could help save many lives if achieved across large populations.
Lead researcher Katherine Mills, an associate professor and vice chair of epidemiology at Tulane University School of Public Health and Tropical Medicine, explained that managing blood pressure often requires repeated visits and ongoing support.
Many doctors have limited time during appointments because they must deal with several health problems at once. Pharmacists and community health workers often have more opportunities to spend time with patients, answer questions, check medicines, and encourage healthy habits.
Pharmacists are especially well placed to help because they understand medicines in great detail. They can work with doctors to adjust medications, recommend dose changes when appropriate, watch for side effects, and remind patients to take their medicines correctly.
Since many people with high blood pressure need several visits before finding the best treatment, pharmacists can provide valuable follow-up care.
Community health workers also have unique strengths. They often live in the same neighborhoods as the people they support. This shared background can help build trust and improve communication. Patients may feel more comfortable discussing their concerns with someone who understands their local community.
Community health workers can also provide education, encourage healthier lifestyles, remind people about appointments, and help them overcome barriers such as transportation or limited access to healthcare. In many places, they also offer a lower-cost way to deliver healthcare support.
Lawrence J. Fine from the National Institutes of Health said the findings highlight the value of team-based care. As blood pressure control rates have been falling in many countries, he believes pharmacists and community health workers can play an even bigger role in helping patients achieve healthier blood pressure levels.
The study also reminds us that controlling high blood pressure is not only the responsibility of doctors. A team approach can give patients more support, more education, and more regular monitoring. This may lead to better long-term health and fewer serious complications.
Researchers hope these findings encourage healthcare systems around the world to make better use of pharmacists and community health workers.
Giving these professionals a larger role could improve care, especially in communities where access to doctors is limited because of cost or distance. Better teamwork could help many more people keep their blood pressure under control and live longer, healthier lives.
If you care about high blood pressure, please read studies that drinking tea could help lower blood pressure, and early time-restricted eating could help improve blood pressure.
